Chai —
Hiring in Palo Alto

We'll be honest: when we first heard about Chai, we thought it was just another AI chatbot trying to ride the ChatGPT wave. Boy, were we wrong. This Palo Alto startup has been quietly building something much more interesting since 2021, and their approach to user-generated AI feels genuinely different.

The Early Bird Advantage

Here's what caught our attention: Chai hit 1 million users in early 2022, before most people even knew what ChatGPT was. That's not luck, that's vision. While everyone else was focused on building the perfect AI assistant, Chai's team saw something else entirely: people don't just want to chat with AI, they want to create their own AI characters and stories.

The numbers back this up too. They've grown from that initial million to over 10 million users by 2025, with reported revenue hitting $70 million annually. For a company with just 11 engineers, that's impressive scaling.

What Makes It Click

The core insight here is brilliant in its simplicity. Instead of building one perfect AI personality, Chai lets users build their own. Their main app is essentially a playground for AI character creation, while their Chaiverse platform gives developers the tools to train and test models on real user interactions.

We love that they're tackling the technical heavy lifting too. Their research spans everything from RLHF to reward models, which means they're not just slapping a pretty interface on someone else's AI. They're building the infrastructure for what they call "user-generated AI" from the ground up.

Room to Grow

With over $55 million in funding and a recent $45 million round, Chai has the runway to execute on their vision. What excites us most is how they're positioning themselves at the intersection of social media and AI, creating a space where creativity meets conversation.

Sure, there are some inconsistencies in their public information (are they in Palo Alto or Newark?), but the core story is solid. They spotted the user-generated AI trend early, built the right tools, and now they're scaling fast. That's exactly the kind of company we like to watch.
